Network Device Interface
Network Device Interface (NDI) is a royalty-free software specification developed by NewTek to enable video-compatible products to communicate, deliver, and receive high-definition video over a computer network in a high-quality, low-latency manner that is frame accurate and suitable for switching in a live Production control room, production environment. Technology NDI is designed to run over gigabit Ethernet, with the NDI codec expected to deliver 1080i HD video at VBR data rates typically around 100 Mbit/s. By default, NDI uses the mDNS (Bonjour (software), Bonjour / Zeroconf) discovery mechanism to advertise sources on a local area network, such that NDI receiving devices can automatically discover and offer those sources, although 2 other discovery modes (NDI Access, NDI Discovery Server) allow for operations across subnets, and without mDNS. Sources are created using an arbitrarily selected TCP port from a range of ports on the NDI send host. When a source is request ...

Software Development Kit
A software development kit (SDK) is a collection of software development tools in one installable package. They facilitate the creation of applications by having a compiler, debugger and sometimes a software framework. They are normally specific to a hardware platform and operating system combination. To create applications with advanced functionalities such as advertisements, push notifications, etc; most application software developers use specific software development kits. Some SDKs are required for developing a platform-specific app. For example, the development of an Android app on the Java platform requires a Java Development Kit. For iOS applications (apps) the iOS SDK is required. For Universal Windows Platform the .NET Framework SDK might be used. There are also SDKs that add additional features and can be installed in apps to provide analytics, data about application activity, and monetization options. Some prominent creators of these types of SDKs include Google ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Character Generator
A character generator, often abbreviated as CG, is a device or software that produces static or animated text (such as news crawls and credits rolls) for keying into a video stream. Modern character generators are computer-based, and they can generate graphics as well as text. History Monoscopes were used as character generators for text mode video rendering in computer displays for a short time in the 1960s. The CBS Laboratories Vidiac, and the A. B. Dick 990 System, were among the earliest character generators for broadcast television. CBS Laboratories later developed the more advanced Vidifont system in preparation for the 1968 US presidential elections, where a rapid method of all-electronic character generation was required so that news outlets could identify unexpected interviewees on the spot. A similar generator using analogue electronics, Anchor, was developed by the BBC in 1970 and used in the general election later that year. Usage In the television busines ...

TriCaster
The NewTek Video Toaster is a combination of hardware and software for the editing and production of NTSC standard-definition video. The plug-in expansion card initially worked with the Amiga 2000 computer and provides a number of BNC connectors on the exposed rear edge that provide connectivity to common analog video sources like VHS VCRs. The related software tools support video switching, chroma keying, character generation, animation, and image manipulation. Together, the hardware and software provided, for a few thousand U.S. dollars, a video editing suite that rivaled the output of contemporary (i.e. early 1990s) professional systems costing ten times as much. It allowed small studios to produce high-quality material and resulted in a cottage industry for video production not unlike the success of the Macintosh in the desktop publishing ( DTP) market only a few years earlier. The Video Toaster won the Emmy Award for Technical Achievement in 1993. Other parts of the or ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
MPEG Transport Stream
MPEG transport stream (MPEG-TS, MTS) or simply transport stream (TS) is a standard digital container format for transmission and storage of audio, video, and Program and System Information Protocol (PSIP) data. It is used in broadcast systems such as DVB, ATSC and IPTV. Transport stream specifies a container format encapsulating packetized elementary streams, with error correction and synchronization pattern features for maintaining transmission integrity when the communication channel carrying the stream is degraded. Transport streams differ from the similarly-named MPEG program stream in several important ways: program streams are designed for reasonably reliable media, such as discs (like DVDs), while transport streams are designed for less reliable transmission, namely terrestrial or satellite broadcast. Further, a transport stream may carry multiple programs. Transport stream is specified in '' MPEG-2 Part 1, Systems'', formally known as '' ISO/IEC standard ...

JPEG XS
JPEG XS (ISO/IEC 21122) is an interoperable, visually lossless, low-latency and lightweight image and video coding system used in professional applications. Applications of the standard include streaming high quality content for virtual reality, drones, autonomous vehicles using cameras, gaming, and broadcasting (SMPTE ST 2022 and ST 2110). In this respect, JPEG XS is unique, being the first ISO codec ever designed for this specific purpose. JPEG XS, built on core technology from both intoPIX and Fraunhofer IIS, is formally standardized as ISO/IEC 21122 by the Joint Photographic Experts Group with the first edition published in 2019. Although not official, the XS acronym was chosen to highlight the ''eXtra Small'' and ''eXtra Speed'' characteristics of the codec. Today, the JPEG committee is still actively working on further improvements to XS, with the second editionA. Descampe et al., "JPEG XS--A New Standard for Visually Lossless Low-Latency Lightweight Image Coding," in Pro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alpha Channel
In computer graphics, alpha compositing or alpha blending is the process of combining one image with a background to create the appearance of partial or full transparency. It is often useful to render picture elements (pixels) in separate passes or layers and then combine the resulting 2D images into a single, final image called the composite. Compositing is used extensively in film when combining computer-rendered image elements with live footage. Alpha blending is also used in 2D computer graphics to put rasterized foreground elements over a background. In order to combine the picture elements of the images correctly, it is necessary to keep an associated ''matte'' for each element in addition to its color. This matte layer contains the coverage information—the shape of the geometry being drawn—making it possible to distinguish between parts of the image where something was drawn and parts that are empty. Although the most basic operation of combining two images is t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
SMPTE 2110
SMPTE 2110 is a suite of standards from the Society of Motion Picture and Television Engineers (SMPTE) that describes how to send digital media over an IP network. SMPTE 2110 is intended to be used within broadcast production and distribution facilities where quality and flexibility are more important than bandwidth efficiency. History SMPTE 2110 was based on the TR-03 and TR-04 work published by the Video Services Forum on 12 November 2015. The first four parts of SMPTE 2110, -10, -20, -21 and -30, were published by SMPTE on 27 November 2017. Standard SMPTE 2110 is specified in several parts: *ST 2110-10 - System architecture and synchronization: essences, RTP, SDP and PTP *ST 2110-20 - Uncompressed video transport, based on SMPTE 2022-6 *ST 2110-21 - Traffic shaping and network delivery timing *ST 2110-22 - Constant Bit-Rate Compressed Video transport *ST 2110-30 - Audio transport, based on AES67 *ST 2110-31 - Transport of AES3 formatted audio *ST 2110-40 - Transport of anci ...
